Hello.
I have a iRedmail server integrated with AD.
I make it following theese instructions 
http://www.iredmail.org/docs/active.directory.html
In my AD i have a user
attributes:
sAMAccountName         = user1
userPrincipalName      = csi at int.mdom.com
proxyAddresses        = mail1 at out.lor.com


i need login with user user1 without domain and then have an address 
mail1 at out.lor.com

i user it in /?etc/?dovecot/?dovecot-?ldap.conf
-?-?-?-?
hosts                   = dc1.int.mdom.com:389
ldap_version            = 3
auth_bind               = yes
dn                      = userksa
dnpass                  = sdjfuihJKHSAJKDHQUWjdskfh
base                    = OU=Users,OU=QOL,DC=int,DC=mdom,DC=com
scope                   = subtree
deref                   = never

user_filter             = (&(objectClass=user)(sAMAccountName=%n) 
(memberof=CN=Mail_Users,OU=Groups,OU=SFP,DC=int,DC=mdom,DC=com))
pass_filter             = (&(objectClass=user)(sAMAccountName=%n) 
(memberof=CN=Mail_Users,OU=Groups,OU=SFP,DC=int,DC=mdom,DC=com))



default_pass_scheme     = CRYPT

user_attrs              = 
=home=/var/vmail/vmail1/%Ld/%Ln/Maildir/,=mail=maildir:/var/vmail/vmail1/%Ld/%Ln/Maildir/

i have tried to do:
#user_filter            = (&(proxyAddresses=%u) 
(objectClass=person)(memberof=CN=Mail_Users,OU=Groups,OU=SFP,DC=int,DC=mdom,DC=com))
#pass_filter            = (&(proxyAddresses=%u) 
(objectClass=person)(memberof=CN=Mail_Users,OU=Groups,OU=SFP,DC=int,DC=mdom,DC=com))

but nothing works.
